Lenovo E570 NM-A831 is a laptop motherboard designed by LCFC and used in the Lenovo E570.

The catalog has 2 schematics, 1 boardview file and 11 BIOS files for it, posted between 2019 and 2024 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 3 board revisions (Rev 1.0, Rev 2.0 and Rev 3.0). Check the revision printed on your PCB before relying on a boardview or flashing a BIOS dump — How to Open .FZ Boardview Files explains why it matters.

The boardview comes in .CAD format. .CAD files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. See How to Open .PCB and .CAD Boardview Files.

With both a schematic and a boardview you can find a net on the diagram and then locate the same part on the board by its reference designator. No Boardview for Your Board? How to Work Without One shows the workflow.

BIOS notes: some archives also hold EC/KBC firmware; versions with a cleaned ME region are included. Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

Also listed under platform CE570.

Frequently asked questions

Which laptops use the NM-A831 motherboard?
File names in the catalog tie NM-A831 to the Lenovo E570. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of NM-A831 do I have?
Files for this board mention Rev 1.0, Rev 2.0 and Rev 3.0. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
How do I open the NM-A831 boardview file?
The boardview for NM-A831 is available as .CAD. .CAD usually needs FlexBV or the matching viewer. See What Is a Boardview File and Why You Need One.
What should I check before flashing the NM-A831 BIOS?
Read the original chip with a programmer and save two copies before writing anything. Some archives include EC/KBC firmware, which may need to be written to a separate chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
